FIELD OF THE INVENTION

The present invention relates to certain aryl-substituted bridged or fused diamine compounds, pharmaceutical compositions containing them, and methods of using the compounds and pharmaceutical compositions for leukotriene A₄ hydrolase (LTA₄H or LTA4H) modulation and for the treatment of disease states, disorders, and conditions mediated by LTA₄H.

BACKGROUND OF THE INVENTION

Inflammation is normally an acute response by the immune system to invasion by microbial pathogens, chemicals or physical injury. In some cases, however, the inflammatory response can progress to a chronic state, and be the cause of inflammatory disease. Therapeutic control of this chronic inflammation in diverse diseases is a major medical need.

Leukotrienes (LT) are biologically active metabolites of arachidonic acid (B. Samuelsson, Science 1983, 220(4597): 568-575) that have been implicated in inflammatory diseases, including asthma (D. A. Munafo et al., J. Clin. Invest. 1994, 93(3):1042-1050; N. Miyahara, et al., Allergol Int., 2006, 55(2): 91-7; E. W. Gelfand, et al., J. Allergy Clin. Immunol. 2006, 117(3): 577-82; K. Terawaki, et al., J. Immunol. 2005, 175(7): 4217-25), inflammatory bowel disease (IBD) (P. Sharon and W. F. Stenson, Gastroenterology 1984, 86(3): 453-460), chronic obstructive pulmonary disease (COPD) (P. J. Barnes, Respiration 2001, 68(5): 441-448), arthritis (R. J. Griffiths et al., Proc. Natl. Acad. Sci. U.S.A. 1995, 92(2): 517-521; F. Tsuji et al., Life Sci. 1998, 64(3): L51-L56), psoriasis (K. Ikai, J. Dermatol. Sci. 1999, 21(3): 135-146; Y. I. Zhu and M. J. Stiller, Skin Pharmacol. Appl. Skin Physiol. 2000, 13(5):235-245) and atherosclerosis (Friedrich, E. B. et al. Arterioscler Thromb Vasc Biol 23, 1761-7 (2003); Subbarao, K. et al. Arterioscler Thromb Vasc Biol 24, 369-75 (2004); Helgadottir, A. et al. Nat Genet 36, 233-9 (2004); Jala, V. R. et al Trends in Immun. 25, 315-322 (2004)). The synthesis of leukotrienes is initiated by the conversion of arachidonic acid to an unstable epoxide intermediate, leukotriene A4 (LTA4), by 5-lipoxygenase (5-LO) (A. W. Ford-Hutchinson et al., Annu. Rev. Biochem. 1994, 63: 383-347). This enzyme is expressed predominantly by cells of myeloid origin, particularly neutrophils, eosinophils, monocytes/macrophages and mast cells (G. K. Reid et al., J. Biol. Chem. 1990, 265(32): 19818-19823). LTA4 can either be conjugated with glutathione by leukotriene C4 (LTC4) synthase to produce the cysteinyl leukotriene, LTC4, or hydrolyzed to the diol, leukotriene B4 (LTB4) (B. Samuelsson, Science 1983, 220(4597): 568-575). LTC4 and its metabolites, LTD4 and LTE4, induce smooth muscle contraction, broncho-constriction and vascular permeability, while LTB4 is a potent chemo-attractant and activator of neutrophils.

The stereospecific hydrolysis of LTA4 to LTB4 is catalyzed by leukotriene A4 hydrolase (LTA₄H), a zinc-containing, cytosolic enzyme. This enzyme is ubiquitously expressed, with high levels in small intestinal epithelial cells, lung, and aorta (B. Samuelsson and C. D. Funk, J. Biol. Chem. 1989, 264(33): 19469-19472). Moderate expression of LTA₄H is observed in leukocytes, particularly neutrophils (T. Yokomizo et al., J. Lipid Mediators Cell Signaling 1995, 12(2,3): 321-332).

Leukotriene B4 is a key pro-inflammatory mediator, able to recruit inflammatory cells, such as neutrophils and eosinophils, as well as activate neutrophils (F. A. Fitzpatrick et al., Ann. N. Y. Acad. Sci. 1994, 714: 64-74; S. W. Crooks and R. A. Stockley, Int. J. Biochem. Cell Biol. 1998, 30(2): 173-178; A. Klein et al., J. Immunol. 2000, 164: 4271-4276). LTB4 mediates its pro-inflammatory effects by binding to G protein-coupled receptors, leukotriene B4 receptor 1 (BLT1) and leukotriene B4 receptor 2 (BLT2) (T. Yokomizo et al., Arch. Biochem. Biophys. 2001, 385(2): 231-241). The receptor first identified, BLT1, binds LTB4 with high affinity, leading to intracellular signaling and chemotaxis. BLT1 is expressed mainly in peripheral leukocytes, particularly neutrophils, eosinophils, macrophages (Huang, W. W. et al. J Exp Med 188, 1063-74 (1998)) and monocytes (Yokomizo, T., Izumi, T. & Shimizu, T. Life Sci 68, 2207-12 (2001)). The murine receptor is also expressed on effector T cells and was recently shown to mediate LTB4-dependent migration of effector CD8⁺ T cells (Goodarzi, K., Goodarzi, M., Tager, A. M., Luster, A. D. & von Andrian, U. H. Nat Immunol 4, 965-73 (2003); Ott, V. L., Cambier, J. C., Kappler, J., Marrack, P. & Swanson, B. J. Nat Immunol 4, 974-81 (2003)), early effector CD4⁺ T helper type 1 (T_(H)1) and T_(H)2 chemotaxis and adhesion to endothelial cells, as well as early effector CD4⁺ and CD8⁺ T cell recruitment in an asthma animal model (Tager, A. M. et al., Nat Immunol 4, 982-90 (2003)). LTB4 receptor BLT2 (S. Wang et al., J. Biol. Chem. 2000, 275(52): 40686-40694; T. Yokomizo et al., J. Exp. Med. 2000, 192(3): 421-431) shares 42% amino acid homology with BLT1, but is more broadly expressed, including in peripheral tissues such as the spleen, ovary and liver, as well as in leukocytes. BLT2 binds LTB4 with lower affinity than BLT1 does, mediates chemotaxis at higher concentrations of LTB4, and differs from BLT1 in its affinity for certain antagonists. While LTB4 receptor antagonists may differ in their affinity for BLT1 versus BLT2, blocking the production of LTB4 using LTA₄H inhibitors would be expected to inhibit the downstream events mediated through both BLT1 and BLT2.

Studies have shown that introduction of exogenous LTB4 into normal tissues can induce inflammatory symptoms (R. D. R. Camp et al., Br. J. Pharmacol. 1983, 80(3): 497-502; R. Camp et al., J. Invest. Dermatol. 1984, 82(2): 202-204). Elevated levels of LTB4 have been observed in a number of inflammatory diseases including IBD, COPD, psoriasis, rheumatoid arthritis (RA), cystic fibrosis and asthma (S. W. Crooks and R. A. Stockley, Int. J. Biochem. Cell Biol. 1998, 30(2): 173-178). Therefore, reduction of LTB4 production by an inhibitor of LTA₄H activity would be predicted to have therapeutic potential in a wide range of diseases.

This idea is supported by a study of LTA₄H -deficient mice that, while otherwise healthy, exhibited markedly decreased neutrophil influx in arachidonic acid-induced ear inflammation and zymosan-induced peritonitis models (R. S. Byrum et al., J. Immunol. 1999, 163(12): 6810-6819). LTA₄H inhibitors have been shown to be effective anti-inflammatory agents in pre-clinical studies. For example, oral administration of LTA₄H inhibitor SC57461 caused inhibition of ionophore-induced LTB4 production in mouse blood ex vivo, and in rat peritoneum in vivo (J. K. Kachur et al., J. Pharm. Exp. Ther. 2002, 300(2), 583-587). Eight weeks of treatment with the same inhibitor compound significantly improved colitis symptoms in cotton top tamarins (T. D. Penning, Curr. Pharm. Des. 2001, 7(3): 163-179). The spontaneous colitis that develops in these animals is very similar to human IBD. The results therefore indicate that LTA₄H inhibitors would have therapeutic utility in this and other human inflammatory diseases.

Events that elicit the inflammatory response include the formation of the pro-inflammatory mediator leukotriene B4. Hydrolase LTA₄H catalyzes the formation of this mediator, and LTA₄H inhibitors block the production of the pro-inflammatory mediator LTB4, thus, providing the ability to prevent and/or treat leukotriene-mediated conditions, such as inflammation. The inflammatory response is characterized by pain, increased temperature, redness, swelling, or reduced function, or by a combination of two or more of these symptoms. Regarding the onset and evolution of inflammation, inflammatory diseases or inflammation-mediated diseases or conditions include, but are not limited to, acute inflammation, allergic inflammation, and chronic inflammation.

Atopic dermatitis (AD) is a chronic inflammatory skin disease that usually occurs in individuals with a personal or family history of atopy. The major features are pruritus and chronic or relapsing eczematous lesions. Complications include bacterial, fungal and viral infections as well as ocular disease. Atopic dermatitis is the most common inflammatory skin disease in children and affects more than 15% of children in the US (Laughter, D., et al., J. Am. Acad. Dermatol. 2000, 43, 649-655). Atopic dermatitis may persist in 60% of adults who were affected as children (Sidbury, R., et al., Dermatol. Clin. 2000, 18(1), 1-11).

Atopic dermatitis has significant societal impact. The family stress related to caring for children with moderate to severe AD may be comparable to the stress seen in families of children with type I diabetes mellitus (Su, J. C., et al., Arch. Dis. Child 1997, 76, 159-162). In the US, the annual cost of medical services and prescription drugs for the treatment of AD/eczema is similar to those for emphysema, psoriasis and epilepsy (Ellis, C. N., et al., J. Am. Acad. Dermatol. 2002, 46, 361-370).

Topical corticosteroids and emollients are the standard of care in the treatment of AD. However, topical steroids are associated with cutaneous complications such as striae, atrophy and telangeictasia that limit the long-term use of these agents (Hanifin, J. M., et al., J. Am. Acad. Dermatol. 2004, 50, 391-404). Emollients have a steroid-sparing effect and are useful for both prevention and maintenance therapy. Crude coal tar and preparations containing coal tar derivatives have also been used for many years in the treatment of AD and have significant cosmetic disadvantages that influence compliance (Hanifin, et al., 2004). Topical doxepin may be a useful short-term adjunctive therapy for the relief of pruritus but sedation and contact dermatitis may complicate its use (Hanifin, et al., 2004).

The topical calcineurin inhibitors tacrolimus (Protopic®) and pimecrolimus (Elidel®) have been shown to reduce the extent, severity and symptoms of AD in adults and children and are approved for use as second-line therapy of AD. However, the recent addition of boxed warnings to the product labels regarding rare cases of malignancy reported in patients treated with topical calcineurin inhibitors limits long term use of these agents in the treatment of AD (Food and Drug Administration [FDA]/Center for Drug Evaluation and Research [CDER] resources page).

Antibiotics are used in the treatment of Staphylococcus aureus infections in patients with AD but have a minimal effect on the dermatitis (Hanifin, et al., 2004). Although sedating antihistamines may be useful if sleep disruption is present, oral antihistamines are generally not effective in treating AD-associated pruritus (Hanifin, et al., 2004). Ultraviolet (UV) phototherapy, including photochemotherapy with psoralen is well established in the treatment of AD but relapse upon cessation of therapy frequently occurs (Hanifin, et al., 2004).

Systemic immunomodulatory therapy with cyclosporine and corticosteroids is effective but can be associated with severe side effects and is generally reserved for patients with severe disease. Systemic corticosteroids are associated with growth retardation in children, avascular necrosis of bone, osteopenia, increased risk of infection, poor wound healing, cataracts, hyperglycemia and hypertension. Cyclosporine is nephrotoxic in a majority of patients and is associated with tremor, hirsutism, hypertension, hyperlipidemia and gum hyperplasia.

While AD that is mild to moderate in severity generally responds to topical therapy, correct use of these therapies and compliance remain a major issue in the clinic. An oral or topical agent lacking the risks associated with corticosteroids and the calcineurin inhibitors would be a welcome addition to the armamentarium of treatments for AD that is mild to moderate in severity. An effective oral or topical therapy with fewer side effects than systemic immunomodulatory therapies and potent topical corticosteroids would fill an unmet medical need in the treatment of AD.

LTB₄ is a potent pro-inflammatory lipid mediator derived from arachidonic acid via the 5-lipoxygenase (5-LO) pathway. LTB₄ is known to be a chemotactic factor and activator of leukocytes, particularly granulocytes and T-cells, and has been implicated in several allergic and inflammatory diseases.

LTB₄ plays a role in AD. LTB₄ levels are elevated in skin lesions and plasma in AD. Reported in vivo and in vitro studies have shown that leukotrienes, especially LTB₄, contribute to the inflammation of the skin in AD through their chemotactic effect on inflammatory cells. LTB₄ receptors are expressed on mast cells, T cells, eosinophils, dendritic cells and macrophages, all of which accumulate in AD lesions. LTB₄ itself is a pruritic agent, and has also been shown to mediate substance P- and nociceptin-induced pruritus, a key component of the itching in AD. LTB₄ also induces proliferation of keratinocytes, an effect which is further potentiated by substance P. Recent reports indicate a role for LTB₄ in development of a Th2 immune response and IgE production. The role of LTB₄ in AD is further supported by beneficial effects of the 5-lipoxygenase inhibitor, zileuton, in a small open-label trial in AD (Woodmansee, D. P., et al., Ann. Allergy Asthma Immunol. 1999, 83, 548-552) and in relieving the pruritus in Sjögren-Larsson syndrome patients who have elevated LTB₄ levels due to an impairment in its degradation (Willemsen, M. A., et al., Eur. J. Pediatr. 2001, 160, 711-717).

Embodiments of this invention have shown dose-dependent inhibition of dermal inflammation and pruritus in a number of preclinical models, as well as inhibition of Th2 responses and IgE production. Oral administration of embodiments of this invention inhibited arachidonic-acid-induced ear inflammation (neutrophil influx and edema) in mice. In a mouse model of cutaneous contact hypersensitivity (CHS), dosing of embodiments of this invention around sensitization decreased IgE production and skin edema upon antigen challenge, while dosing prior to challenge decreased pruritus. Oral dosing of embodiments of this invention was also efficacious in reducing pruritus in mice induced by compound 48/80, substance P or IgE-antigen interaction in the skin.

LTA₄H inhibitors are hypothesized to specifically block the production of LTB₄ from LTA₄, without affecting the biosynthesis of lipoxins, which are also produced from LTA₄. Increasing or maintaining lipoxin A₄ (LXA₄) production may have beneficial therapeutic effects in dermal inflammation as it has been reported that topical application of a stable lipoxin analogue inhibits edema, granulocyte infiltration and epidermal hyperproliferation in murine skin inflammation models. 5-LO inhibitors block the pathway upstream of LTA₄. This would be expected to lead to a block in not only synthesis of LTA₄, LTB₄ and cysteinyl leukotrienes, but also LXA₄.

Embodiments of this invention have been studied in a number of in vivo skin (and peritoneal) inflammation models including arachidonic acid-induced ear inflammation, zymosan-induced peritonitis, fluorescein isothiocyanate (FITC)-induced cutaneous contact hypersensitivity (CHS), and cutaneous itch induced by substance P, compound 48/80 and IgE/antigen interaction. Pharmacology models were also performed with embodiments of this invention to assess their effects on the development of Th2 immune responses and allergic lung inflammation, including ovalbumin (OVA) sensitization model and OVA sensitization and airway challenge models. Additional pharmacological profiling demonstrated efficacy in models of acute and chronic TNBS-induced colitis and collagen-induced arthritis.

An allergy is an abnormal reaction to an allergen (an ordinarily harmless substance) that triggers an abnormal response in a sensitized individual. Allergic rhinitis is an inflammation of the mucus membranes of the nose that occurs in response to an airborne antigen (allergen). Allergic rhinitis, also called allergic rhinoconjunctivitis, is characterized by frequent or repetitive sneezing, runny or congested nose, and pruritus of the nose, eyes and throat. It may also be associated with other symptoms such as headache, impaired smell, postnasal drip, conjunctival symptoms (e.g., itchy watery eyes), sinusitis and other complicating respiratory symptoms. Depending upon the time of exposure, allergic rhinitis can be classified as perennial, seasonal or occupational.

Embodiments of this invention have shown dose-dependent inhibition of lung inflammation in a number of pre-clinical models, as well as inhibition of Th2 responses and IgE production. In addition, embodiments of this invention inhibit pruritus induced by allergen/IgE interaction.

Based upon the well-described leukotriene biosynthesis pathway (FIG. 1), LTA₄H inhibitors are hypothesized to specifically block the production of LTB₄ from LTA₄, without affecting the biosynthesis of lipoxins, which are also produced from LTA₄. Lipoxins, such as LXA₄, have been the focus of intense study and are known to play a key role as natural anti-inflammatory agents and key mediators of the natural process of resolving an inflammatory response. Furthermore, production of endogenous LXA₄ has been described in a variety of inflammatory diseases and lower levels of LXA₄ have been found in patients with severe versus moderate asthma. These data are consistent with the proposition that LXA₄ plays an important role in resolution of acute inflammation. Unlike LTA₄ inhibitors, 5-LO inhibitors block this pathway upstream of LTA₄. This would lead to a block in not only synthesis of LTA₄, LTB₄ and cysteinyl leukotrienes, but also LXA₄. Furthermore, there is a possibility that LTA₄H inhibitors result in a buildup of LTA₄, and pathway shunting to pro-inflammatory cysteinyl leukotrienes, although to date there is no known data to support this possibility. Embodiments of this invention have shown in a model of zymosan-induced peritonitis that inhibition of LTB₄ production leads to an increase in LXA₄ production.

Neutrophil infiltration is a prominent feature of severe asthma. Zileuton (Zyflo®) has been suggested to be efficacious is severe asthma patients, while CysLT antagonists (i.e., Montelukast/Singulair®) are not. Embodiments of this invention inhibit Th2 T cell responses and IgE production in animal models of asthma.

Embodiments of this invention inhibited sensitization to antigen and reduced inflammatory responses to airway allergen challenge in sensitized mice, leading to dose-dependent decreases in airway hyperreactivity, airway recruitment of inflammatory cells, and reductions in inteleukin (IL)-5, IL-13, and antigen-specific IgE production.

In trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats, embodiments of this invention had significant inhibitory effects on colonic inflammation, including macroscopic colonic injury, inflammatory cell content, and levels of tumor necrosis factor alpha (TNF-α), LTB₄, and IL-6. LTA₄H inhibition by embodiments of this invention also significantly attenuated the joint inflammation and swelling associated with the destruction of collagen in murine models of arthritis.

Embodiments of this invention are expected to find utility in treating skin burns, such as those due to sunburn or some other agent.

Embodiments of this invention are expected to find utility in treating also any one or a combination of atopic dermatitis, contact dermatitis, acne (T. Alestas, et al., J. Mol. Med. 2006, 84(1): 75-87; Ch. C. Zouboulis, et al., Dermatology, 2005, 210(1): 36-8; Arch. Dermatol. 2003, 139(5): 668-70), myocardial infarction (A. Helgadottir, et al., Nat.

Dermatol. 2004, 123(1): 196-201, 2001, 117(6): 1621-26; gingivitis (G. Emingil, et al., J. Periodontol. 2001, 72(8): 1025-31), uveitis (T. Liao, et al., Invest. Ophthalmol. Vis.

Care Med. 2003, 167(8): 1109-12), upper grastrointestinal cancer (X. Chen, et al., Curr. Cancer Drug Targets 2004, 4(3): 267-83; J. natl. cancer inst. 2003, 95(14): 1053-61), and sepsis (H. Nakae, et al., Res. Commun. Chem. Pathol. Pharmacol. 1994, 83(2): 151-6, 84(3): 271-81), and skin burns.

DETAILED DESCRIPTION OF INVENTION AND ITS PREFERRED EMBODIMENTS

For the sake of brevity, the disclosures of the publications, including patents and patent applications, cited anywhere in this specification are herein incorporated by reference.

As used herein, the terms “including”, “containing” and “comprising” are used herein in their open, non-limiting sense.

The term “alkyl” refers to a straight- or branched-chain alkyl group having from 1 to 12 carbon atoms in the chain. Examples of alkyl groups include methyl (Me, which also may be structurally depicted by a / symbol), ethyl (Et), n-propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl (tBu), pentyl, isopentyl, tert-pentyl, hexyl, isohexyl, and groups that in light of the ordinary skill in the art and the teachings provided herein would be considered equivalent to any one of the foregoing examples.

The term “cycloalkyl” refers to a saturated or partially saturated, monocyclic, fused polycyclic, or spiro polycyclic carbocycle having from 3 to 12 ring atoms per carbocycle. Illustrative examples of cycloalkyl groups include the following entities, in the form of properly bonded moieties:

A “heterocycloalkyl” refers to a monocyclic, or fused, bridged, or spiro polycyclic ring structure that is saturated or partially saturated and has from 3 to 12 ring atoms per ring structure selected from carbon atoms and up to three heteroatoms selected from nitrogen, oxygen, and sulfur. The ring structure may optionally contain up to two oxo groups on carbon or sulfur ring members. Illustrative entities, in the form of properly bonded moieties, include:

The term “heteroaryl” refers to a monocyclic, fused bicyclic, or fused polycyclic aromatic heterocycle (ring structure having ring atoms selected from carbon atoms and up to four heteroatoms selected from nitrogen, oxygen, and sulfur) having from 3 to 12 ring atoms per heterocycle. Illustrative examples of heteroaryl groups include the following entities, in the form of properly bonded moieties:

Those skilled in the art will recognize that the species of cycloalkyl, heterocycloalkyl, and heteroaryl groups listed or illustrated above are not exhaustive, and that additional species within the scope of these defined terms may also be selected.

The term “halogen” represents chlorine, fluorine, bromine, or iodine. The term “halo” represents chloro, fluoro, bromo, or iodo.

The term “substituted” means that the specified group or moiety bears one or more substituents. The term “unsubstituted” means that the specified group bears no substituents. The term “optionally substituted” means that the specified group is unsubstituted or substituted by one or more substituents. Where the term “substituted” is used to describe a structural system, unless otherwise indicated, the substitution is meant to occur at any valency-allowed position on the system.

Any formula given herein is intended to represent compounds having structures depicted by the structural formula as well as certain variations or forms. In particular, compounds of any formula given herein may have asymmetric centers and therefore exist in different enantiomeric forms. All optical isomers and stereoisomers of the compounds of the general formula, and mixtures thereof, are considered within the scope of the formula. Thus, any formula given herein is intended to represent a racemate, one or more enantiomeric forms, one or more diastereomeric forms, one or more atropisomeric forms, and mixtures thereof. Furthermore, certain structures may exist as geometric isomers (i.e., cis and trans isomers), as tautomers, or as atropisomers. Additionally, any formula given herein is intended to represent hydrates, solvates, and polymorphs of such compounds, and mixtures thereof.

Certain formulae given herein are meso compounds, which are compounds that possess asymmetric centers (in this case, asymmetric carbons), but which are achiral molecules. Such compounds are named herein as meso compounds. In some cases, meso compounds are depicted and named herein with a specific stereochemical configuration. However, one skilled in the art will recognize the meso nature of such compounds. Examples include meso-endo-(8-Methanesulfonyl-8-aza-bicyclo[3.2. 1]oct-3-yl)-{2-[4-(6-methyl-benzothiazol-2-yloxy)-phenoxy]-ethyl}-amine and meso-endo-3-{2-[4-(4-Chloro-benzothiazol-2-yloxy)-phenoxy]-ethylamino}-8-aza-bicyclo[3.2.1]octane-8-carboxylic acid amide.

To provide a more concise description, some of the quantitative expressions given herein are not qualified with the term “about”. It is understood that, whether the term “about” is used explicitly or not, every quantity given herein is meant to refer to the actual given value, and it is also meant to refer to the approximation to such given value that would reasonably be inferred based on the ordinary skill in the art, including equivalents and approximations due to the experimental and/or measurement conditions for such given value. Whenever a yield is given as a percentage, such yield refers to a mass of the entity for which the yield is given with respect to the maximum amount of the same entity that could be obtained under the particular stoichiometric conditions. Concentrations that are given as percentages refer to mass ratios, unless indicated differently.

Reference to a chemical entity herein stands for a reference to any one of: (a) the actually recited form of such chemical entity, and (b) any of the forms of such chemical entity in the medium in which the compound is being considered when named. For example, reference herein to a compound such as R—COOH, encompasses reference to any one of, for example, R—COOH_((S)), R—COOH_((SOI)), and R—COO⁻ _((SOI)). In this example, R—COOH_((S)) refers to the solid compound, as it could be for example in a tablet or some other solid pharmaceutical composition or preparation; R—COOH_((SOI)) refers to the undissociated form of the compound in a solvent; and R—COO⁻ _((SOI)) refers to the dissociated form of the compound in a solvent, such as the dissociated form of the compound in an aqueous environment, whether such dissociated form derives from R—COOH, from a salt thereof, or from any other entity that yields R—COO⁻ upon dissociation in the medium being considered. In another example, an expression such as “exposing an entity to compound of formula R—COOH” refers to the exposure of such entity to the form, or forms, of the compound R—COOH that exists, or exist, in the medium in which such exposure takes place. In still another example, an expression such as “reacting an entity with a compound of formula R—COOH” refers to the reacting of (a) such entity in the chemically relevant form, or forms, of such entity that exists, or exist, in the medium in which such reacting takes place, with (b) the chemically relevant form, or forms, of the compound R—COOH that exists, or exist, in the medium in which such reacting takes place. In this regard, if such entity is for example in an aqueous environment, it is understood that the compound R—COOH is in such same medium, and therefore the entity is being exposed to species such as R—COOH_((aq)) and/or R—COO⁻ _((aq)), where the subscript “(aq)” stands for “aqueous” according to its conventional meaning in chemistry and biochemistry. A carboxylic acid functional group has been chosen in these nomenclature examples; this choice is not intended, however, as a limitation but it is merely an illustration. It is understood that analogous examples can be provided in terms of other functional groups, including but not limited to hydroxyl, basic nitrogen members, such as those in amines, and any other group that interacts or transforms according to known manners in the medium that contains the compound. Such interactions and transformations include, but are not limited to, dissociation, association, tautomerism, solvolysis, including hydrolysis, solvation, including hydration, protonation, and deprotonation.

In another example, a zwitterionic compound is encompassed herein by referring to a compound that is known to form a zwitterion, even if it is not explicitly named in its zwitterionic form. Terms such as zwitterion, zwitterions, and their synonyms zwitterionic compound(s) are standard IUPAC-endorsed names that are well known and part of standard sets of defined scientific names. In this regard, the name zwitterion is assigned the name identification CHEBI:27369 by the Chemical Entities of Biological Inerest (ChEBI) dictionary of molecular entities. As generally well known, a zwitterion or zwitterionic compound is a neutral compound that has formal unit charges of opposite sign. Sometimes these compounds are referred to by the term “inner salts”. Other sources refer to these compounds as “dipolar ions”, although the latter term is regarded by still other sources as a misnomer. As a specific example, aminoethanoic acid (the amino acid glycine) has the formula H₂NCH₂COOH, and it exists in some media (in this case in neutral media) in the form of the zwitterion ⁺H₃NCH₂COO⁻. Zwitterions, zwitterionic compounds, inner salts and dipolar ions in the known and well established meanings of these terms are within the scope of this invention, as would in any case be so appreciated by those of ordinary skill in the art. Because there is no need to name each and every embodiment that would be recognized by those of ordinary skill in the art, no structures of the zwitterionic compounds that are associated with the compounds of this invention are given explicitly herein. They are, however, part of the embodiments of this invention. No further examples in this regard are provided herein because the interactions and transformations in a given medium that lead to the various forms of a given compound are known by any one of ordinary skill in the art.

Any formula given herein is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, chlorine, and iodine, such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, ³⁶Cl, ¹²⁵Cl, respectively. Such isotopically labelled compounds are useful in metabolic studies (preferably with ¹⁴C), reaction kinetic studies (with, for example ²H or ³H), detection or imaging techniques [such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT)] including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an ¹⁸F or ¹¹C labeled compound may be particularly preferred for PET or SPECT studies. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

When referring to any formula given herein, the selection of a particular moiety from a list of possible species for a specified variable is not intended to define the same choice of the species for the variable appearing elsewhere. In other words, where a variable appears more than once, the choice of the species from a specified list is independent of the choice of the species for the same variable elsewhere in the formula, unless stated otherwise.

By way of a first example on substituent terminology, if substituent S¹ _(example) is one of S₁ and S₂, and substituent S² _(example) is one of S₃ and S₄, then these assignments refer to embodiments of this invention given according to the choices S¹ _(example) is S₁ and S² _(example) is S₃; S¹ _(example) is S₁ and S² _(example) is S₄; S¹ _(example) is S₂ and S² _(example) is S₃; S¹ _(example) is S₂ and S² _(example) is S₄; and equivalents of each one of such choices. The shorter terminology “S¹ _(example) is one of S₁ and S₂, and S² _(example) is one of S₃ and S₄” is accordingly used herein for the sake of brevity, but not by way of limitation. The foregoing first example on substituent terminology, which is stated in generic terms, is meant to illustrate the various substituent assignments described herein. The foregoing convention given herein for substituents extends, when applicable, to members such as R¹⁻², A, D, Q, X, Y, Z, m, n, p, and q, and any other generic substituent symbol used herein.

Furthermore, when more than one assignment is given for any member or substituent, embodiments of this invention comprise the various groupings that can be made from the listed assignments, taken independently, and equivalents thereof. By way of a second example on substituent terminology, if it is herein described that substituent S_(example) is one of S₁, S₂, and S₃, this listing refers to embodiments of this invention for which S_(example) is S₁; S_(example) is S₂; S_(example) is S₃; S_(example) is one of S₁ and S₂; S_(example) is one of S₁ and S₃; S_(example) is one of S₂ and S₃; S_(example) is one of S₁, S₂ and S₃; and S_(example) is any equivalent of each one of these choices. The shorter terminology “S_(example) is one of S₁, S₂, and S₃” is accordingly used herein for the sake of brevity, but not by way of limitation. The foregoing second example on substituent terminology, which is stated in generic terms, is meant to illustrate the various substituent assignments described herein. The foregoing convention given herein for substituents extends, when applicable, to members such as R¹⁻², A, D, Q, X, Y, Z, m, n, p, and q, and any other generic substituent symbol used herein.

The nomenclature “C_(i-j)” with j>i, when applied herein to a class of substituents, is meant to refer to embodiments of this invention for which each and every one of the number of carbon members, from i to j including i and j, is independently realized. By way of example, the term C₁₋₃ refers independently to embodiments that have one carbon member (C₁), embodiments that have two carbon members (C₂), and embodiments that have three carbon members (C₃).

The term C_(n-m)alkyl refers to an aliphatic chain, whether straight or branched, with a total number N of carbon members in the chain that satisfies n≦N≦m, with m>n.

Any disubstituent referred to herein is meant to encompass the various attachment possibilities when more than one of such possibilities are allowed. For example, reference to disubstituent -A-B—, where A≠B, refers herein to such disubstituent with A attached to a first substituted member and B attached to a second substituted member, and it also refers to such disubstituent with A attached to the second substituted member and B attached to the first substituted member.

According to the foregoing interpretive considerations on assignments and nomenclature, it is understood that explicit reference herein to a set implies, where chemically meaningful and unless indicated otherwise, independent reference to embodiments of such set, and reference to each and every one of the possible embodiments of subsets of the set referred to explicitly.

The invention includes also pharmaceutically acceptable salts of the compounds represented by Formula (I), preferably of those described above and of the specific compounds exemplified herein, and methods using such salts.

A “pharmaceutically acceptable salt” is intended to mean a salt of a free acid or base of a compound represented by Formula (I) that is non-toxic, biologically tolerable, or otherwise biologically suitable for administration to the subject. See, generally, S. M. Berge, et al., “Pharmaceutical Salts”, J. Pharm. Sci., 1977, 66:1-19, and Handbook of Pharmaceutical Salts, Properties, Selection, and Use, Stahl and Wermuth, Eds., Wiley-VCH and VHCA, Zurich, 2002. Preferred pharmaceutically acceptable salts are those that are pharmacologically effective and suitable for contact with the tissues of patients without undue toxicity, irritation, or allergic response. A compound of Formula (I) may possess a sufficiently acidic group, a sufficiently basic group, or both types of functional groups, and accordingly react with a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt. Examples of pharmaceutically acceptable salts include sulfates, pyrosulfates, bisulfates, sulfites, bisulfites, phosphates, monohydrogen-phosphates, dihydrogenphosphates, metaphosphates, pyrophosphates, chlorides, bromides, iodides, acetates, propionates, decanoates, caprylates, acrylates, formates, isobutyrates, caproates, heptanoates, propiolates, oxalates, malonates, succinates, suberates, sebacates, fumarates, maleates, butyne-1,4-dioates, hexyne-1,6-dioates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, hydroxybenzoates, methoxybenzoates, phthalates, sulfonates, xylenesulfonates, phenylacetates, phenylpropionates, phenylbutyrates, citrates, lactates, γ-hydroxybutyrates, glycolates, tartrates, methane-sulfonates, propanesulfonates, naphthalene-1-sulfonates, naphthalene-2-sulfonates, and mandelates.

If the compound of Formula (I) contains a basic nitrogen, the desired pharmaceutically acceptable salt may be prepared by any suitable method available in the art, for example, treatment of the free base with an inorganic acid, such as hydrochloric acid, hydrobroric acid, sulfuric acid, sulfamic acid, nitric acid, boric acid, phosphoric acid, and the like, or with an organic acid, such as acetic acid, phenylacetic acid, propionic acid, stearic acid, lactic acid, ascorbic acid, maleic acid, hydroxymaleic acid, isethionic acid, succinic acid, valeric acid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, oleic acid, palmitic acid, lauric acid, a pyranosidyl acid, such as glucuronic acid or galacturonic acid, an alpha-hydroxy acid, such as mandelic acid, citric acid, or tartaric acid, an amino acid, such as aspartic acid or glutamic acid, an aromatic acid, such as benzoic acid, 2-acetoxybenzoic acid, naphthoic acid, or cinnamic acid, a sulfonic acid, such as laurylsulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, ethanesulfonic acid, any compatible mixture of acids such as those given as examples herein, and any other acid and mixture thereof that are regarded as equivalents or acceptable substitutes in light of the ordinary level of skill in this technology.

If the compound of Formula (I) is an acid, such as a carboxylic acid or sulfonic acid, the desired pharmaceutically acceptable salt may be prepared by any suitable method, for example, treatment of the free acid with an inorganic or organic base, such as an amine (primary, secondary or tertiary), an alkali metal hydroxide, alkaline earth metal hydroxide, any compatible mixture of bases such as those given as examples herein, and any other base and mixture thereof that are regarded as equivalents or acceptable substitutes in light of the ordinary level of skill in this technology. Illustrative examples of suitable salts include organic salts derived from amino acids, such as glycine and arginine, ammonia, carbonates, bicarbonates, primary, secondary, and tertiary amines, and cyclic amines, such as benzylamines, pyrrolidines, piperidine, morpholine, and piperazine, and inorganic salts derived from sodium, calcium, potassium, magnesium, manganese, iron, copper, zinc, aluminum, and lithium.

The invention also relates to pharmaceutically acceptable prodrugs of the compounds of Formula (I), and methods employing such pharmaceutically acceptable prodrugs. The term “prodrug” means a precursor of a designated compound that, following administration to a subject, yields the compound in vivo via a chemical or physiological process such as solvolysis or enzymatic cleavage, or under physiological conditions (e.g., a prodrug on being brought to physiological pH is converted to the compound of Formula (I)). A “pharmaceutically acceptable prodrug” is a prodrug that is non-toxic, biologically tolerable, and otherwise biologically suitable for administration to the subject. Illustrative procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.

Examples of prodrugs include compounds having an amino acid residue, or a polypeptide chain of two or more (e.g., two, three or four) amino acid residues, covalently joined through an amide or ester bond to a free amino, hydroxy, or carboxylic acid group of a compound of Formula (I). Examples of amino acid residues include the twenty naturally occurring amino acids, commonly designated by three letter symbols, as well as 4-hydroxyproline, hydroxylysine, demosine, isodemosine, 3-methylhistidine, norvalin, beta-alanine, gamma-aminobutyric acid, citrulline homocysteine, homoserine, ornithine and methionine sulfone.

Additional types of prodrugs may be produced, for instance, by derivatizing free carboxyl groups of structures of Formula (I) as amides or alkyl esters. Examples of amides include those derived from ammonia, primary C₁₋₆alkyl amines and secondary di(C₁₋₆alkyl) amines. Secondary amines include 5- or 6-membered heterocycloalkyl or heteroaryl ring moieties. Examples of amides include those that are derived from ammonia, C₁₋₃alkyl primary amines, and di(C₁₋₂alkyl)amines. Examples of esters of the invention include C₁₋₇alkyl, C₅₋₇cycloalkyl, phenyl, and phenyl(C₁₋₆alkyl) esters. Preferred esters include methyl esters. Prodrugs may also be prepared by derivatizing free hydroxy groups using groups including hemisuccinates, phosphate esters, dimethylaminoacetates, and phosphoryloxymethyloxycarbonyls, following procedures such as those outlined in Adv. Drug Delivery Rev. 1996, 19, 115. Carbamate derivatives of hydroxy and amino groups may also yield prodrugs. Carbonate derivatives, sulfonate esters, and sulfate esters of hydroxy groups may also provide prodrugs. Derivatization of hydroxy groups as (acyloxy)methyl and (acyloxy)ethyl ethers, wherein the acyl group may be an alkyl ester, optionally substituted with one or more ether, amine, or carboxylic acid functionalities, or where the acyl group is an amino acid ester as described above, is also useful to yield prodrugs. Prodrugs of this type may be prepared as described in J. Med. Chem. 1996, 39, 10. Free amines can also be derivatized as amides, sulfonamides or phosphonamides. All of these prodrug moieties may incorporate groups including ether, amine, and carboxylic acid functionalities.

The present invention also relates to pharmaceutically active metabolites of compounds of Formula (I), and uses of such metabolites in the methods of the invention. A “pharmaceutically active metabolite” means a pharmacologically active product of metabolism in the body of a compound of Formula (I) or salt thereof. Prodrugs and active metabolites of a compound may be determined using routine techniques known or available in the art. See, e.g., Bertolini, et al., J. Med. Chem. 1997, 40, 2011-2016; Shan, et al., J. Pharm. Sci. 1997, 86 (7), 765-767; Bagshawe, Drug Dev. Res. 1995, 34, 220-230; Bodor, Adv. Drug Res. 1984, 13, 224-331; Bundgaard, Design of Prodrugs (Elsevier Press, 1985); and Larsen, Design and Application of Prodrugs, Drug Design and Development (Krogsgaard-Larsen, et al., eds., Harwood Academic Publishers, 1991).

The compounds of Formula (I) and their pharmaceutically acceptable salts, pharmaceutically acceptable prodrugs, and pharmaceutically active metabolites (collectively, “active agents”) of the present invention are useful as LTA₄H modulators in the methods of the invention. Such methods for modulating LTA₄H activity comprise exposing LTA4H to an effective amount of at least one chemical entity selected from compounds of Formula (I), pharmaceutically acceptable salts of compounds of Formula (I), pharmaceutically acceptable prodrugs of compounds of Formula (I), and pharmaceutically active metabolites of compounds of Formula (I). Embodiments of this invention inhibit LTA₄H activity.

In some embodiments, the LTA₄H is in a subject with a disease, disorder, or medical condition mediated by LTA₄H activity, such as those described herein. Symptoms,or disease states are intended to be included within the scope of “medical conditions, disorders, or diseases.”

Accordingly, the invention relates to methods of using the active agents described herein to treat subjects diagnosed with or suffering from a disease, disorder, or condition mediated through LTA₄H activity, such as inflammation. Active agents according to the invention may therefore be used as anti-inflammatory agent(s).

In some embodiments, an active agent of the present invention is administered to treat inflammation. Inflammation may be associated with various diseases, disorders, or conditions, such as inflammatory disorders, allergic disorders, dermatological disorders, autoimmune disease, lymphatic disorders, and immunodeficiency disorders, including the more specific conditions and diseases given below. Regarding the onset and evolution of inflammation, inflammatory diseases or inflammation-mediated diseases or conditions include, but are not limited to, acute inflammation, allergic inflammation, and chronic inflammation.

Illustrative types of inflammation treatable with an LTA₄H modulating agent include inflammation due to any one of a plurality of conditions such as allergy, asthma, nasal polyps, allergic rhinitis, nasal itch, ocular inflammation (e.g., post-surgical ocular inflammation), conjunctivitis, uveitis, dry eye, psoriasis, pruritis, itch, itchy skin, atopic dermatitis, urticaria (hives), contact dermatitis, scleroderma, skin burns, acne, inflammatory bowel diseases (including colitis, Crohn's disease and ulcerative colitis), chronic obstructed pulmonary disease (COPD), atherosclerosis, arthritis (including rheumatoid arthritis), multiple sclerosis, myocardial infarction, stroke, pain, gingivitis, bronchitis, cystic fibrosis, upper gastrointestinal cancer, sepsis, autoimmune thyroid diseases, and immune-mediated (also known as type 1) diabetes mellitus and lupus, which are characterized by excessive or prolonged inflammation at some stage of the disease. Other autoimmune diseases that lead to inflammation include Myasthenia gravis, autoimmune neuropathies, such as Guillain-Barré, autoimmune uveitis, autoimmune hemolytic anemia, pernicious anemia, autoimmune thrombocytopenia, temporal arteritis, anti-phospholipid syndrome, vasculitides, such as Wegener's granulomatosis, Behcet's disease, dermatitis herpetiformis, pemphigus vulgaris, vitiligio, primary biliary cirrhosis, autoimmune hepatitis, autoimmune oophoritis and orchitis, autoimmune disease of the adrenal gland, polymyositis, dermatomyositis, spondyloarthropathies, such as ankylosing spondylitis, and Sjogren's syndrome.

Pruritis treatable with an LTA₄H-modulating agent according to the invention includes that which is a symptom of allergic cutaneous diseases (such as atopic dermatitis and hives) and other metabolic disorders (such as chronic renal failure, hepatic cholestasis, and diabetes mellitus).

In other embodiments, an active agent of the present invention is administered to treat allergy, asthma, autoimmune diseases, pruritis, inflammatory bowel disease, ulcerative colitis, or cardiovascular disease, including atherosclerosis and prevention of myocardial infarction.

Thus, the active agents may be used to treat subjects diagnosed with or suffering from a disease, disorder, or condition mediated through LTA₄H activity. The term “treat” or “treating” as used herein is intended to refer to administration of an active agent or composition of the invention to a subject for the purpose of effecting a therapeutic or prophylactic benefit through modulation of LTA₄H activity. Treating includes reversing, ameliorating, alleviating, inhibiting the progress of, lessening the severity of, or preventing a disease, disorder, or condition, or one or more symptoms of such disease, disorder or condition mediated through modulation of LTA₄H activity. The term “subject” refers to a mammalian patient in need of such treatment, such as a human. “Modulators” include both inhibitors and activators, where “inhibitors” refer to compounds that decrease, prevent, inactivate, desensitize or down-regulate LTA₄H expression or activity, and “activators” are compounds that increase, activate, facilitate, sensitize, or up-regulate LTA₄H expression or activity. Embodiments of chemical entities according to this invention are LTA₄H-modulating chemical entities.

In treatment methods according to the invention, an effective amount of at least one active agent according to the invention is administered to a subject suffering from or diagnosed as having such a disease, disorder, or condition. An “effective amount” means an amount or dose sufficient to generally bring about the desired therapeutic or prophylactic benefit in patients in need of such treatment for the designated disease, disorder, or condition. When referring to modulating the target receptor, an “effective amount” means an amount sufficient to at least affect the activity of such receptor. Measuring the activity of the target receptor may be performed by routine analytical methods. Target receptor modulation is useful in a variety of settings, including assays.

In addition, effective amounts or doses of the active agents of the present invention may be ascertained by routine methods such as modeling, dose escalation studies or clinical trials, and by taking into consideration routine factors, e.g., the mode or route of administration or drug delivery, the pharmacokinetics of the agent, the severity and course of the disease, disorder, or condition, the subject's previous or ongoing therapy, the subject's health status and response to drugs, and the judgment of the treating physician. An exemplary dose is in the range of from about 0.001 to about 200 mg of active agent per kg of subject's body weight per day, preferably about 0.05 to 100 mg/kg/day, or about 1 to 35 mg/kg/day, or about 0.1 to 10 mg/kg daily in single or divided dosage units (e.g., BID, TID, QID). For a 70-kg human, an illustrative range for a suitable dosage amount is from about 0.05 to about 7 g/day, or about 0.2 to about 2.5 g/day.

Once improvement of the patient's disease, disorder, or condition has occurred, the dose may be adjusted for preventative or maintenance treatment. For example, the dosage or the frequency of administration, or both, may be reduced as a function of the symptoms, to a level at which the desired therapeutic or prophylactic effect is maintained. Of course, if symptoms have been alleviated to an appropriate level, treatment may cease. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.

In addition, the active agents of the invention may be used in combination with additional active ingredients in the treatment of the above conditions. The additional active ingredients may be coadministered separately with an active agent of Formula (I) or included with such an agent in a pharmaceutical composition according to the invention. In an exemplary embodiment, additional active ingredients are those that are known or discovered to be effective in the treatment of conditions, disorders, or diseases mediated by LTA₄H activity, such as another LTA₄H modulator or a compound active against another target associated with the particular condition, disorder, or disease. The combination may serve to increase efficacy (e.g., by including in the combination a compound potentiating the potency or effectiveness of an agent according to the invention), decrease one or more side effects, or decrease the required dose of the active agent according to the invention.

Other embodiments of this invention further comprise the administration of at least one CysLT antagonist and/or at least one CysLT synthesis inhibitor. In some embodiments of this invention, such LTA₄H modulator and CysLT antagonist and/or CysLT synthesis inhibitor are coadministered. Examples of CysLT antagonists are CysLT1 and CysLT2 antagonists.

The active agents of the invention are used, alone or in combination with one or more additional active ingredients, to formulate pharmaceutical compositions of the invention. A pharmaceutical composition of the invention comprises an effective amount of at least one active agent in accordance with the invention. Such compositions may further comprise a pharmaceutically acceptable excipient.

A “pharmaceutically acceptable excipient” refers to a substance that is non-toxic, biologically tolerable, and otherwise biologically suitable for administration to a subject, such as an inert substance, added to a pharmacological composition or otherwise used as a vehicle, carrier, or diluent to facilitate administration of a agent and that is compatible therewith. Examples of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils, and polyethylene glycols.

Delivery forms of the pharmaceutical compositions containing one or more dosage units of the active agents may be prepared using suitable pharmaceutical excipients and compounding techniques known or that become available to those skilled in the art. The compositions may be administered in the inventive methods by a suitable route of delivery, e.g., oral, parenteral, rectal, topical, or ocular routes, or by inhalation.

The preparation may be in the form of tablets, capsules, sachets, dragees, powders, granules, lozenges, powders for reconstitution, liquid preparations, or suppositories. Preferably, the compositions are formulated for intravenous infusion, topical administration, or oral administration.

For oral administration, the active agents of the invention can be provided in the form of tablets or capsules, or as a solution, emulsion, or suspension. To prepare the oral compositions, the active agents may be formulated to yield a dosage of, e.g., from about 0.05 to about 50 mg/kg daily, or from about 0.05 to about 20 mg/kg daily, or from about 0.1 to about 10 mg/kg daily.

Oral tablets may include the active ingredient(s) mixed with compatible pharmaceutically acceptable excipients such as diluents, disintegrating agents, binding agents, lubricating agents, sweetening agents, flavoring agents, coloring agents and preservative agents. Suitable inert fillers include sodium and calcium carbonate, sodium and calcium phosphate, lactose, starch, sugar, glucose, methyl cellulose, magnesium stearate, mannitol, sorbitol, and the like. Exemplary liquid oral excipients include ethanol, glycerol, water, and the like. Starch, polyvinyl-pyrrolidone (PVP), sodium starch glycolate, microcrystalline cellulose, and alginic acid are exemplary disintegrating agents. Binding agents may include starch and gelatin. The lubricating agent, if present, may be magnesium stearate, stearic acid or talc. If desired, the tablets may be coated with a material such as glyceryl monostearate or glyceryl distearate to delay absorption in the gastrointestinal tract, or may be coated with an enteric coating.

Capsules for oral administration include hard and soft gelatin capsules. To prepare hard gelatin capsules, active ingredient(s) may be mixed with a solid, semi-solid, or liquid diluent. Soft gelatin capsules may be prepared by mixing the active ingredient with water, an oil such as peanut oil or olive oil, liquid paraffin, a mixture of mono and di-glycerides of short chain fatty acids, polyethylene glycol 400, or propylene glycol.

Liquids for oral administration may be in the form of suspensions, solutions, emulsions or syrups or may be lyophilized or presented as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid compositions may optionally contain: pharmaceutically-acceptable excipients such as suspending agents (for example, sorbitol, methyl cellulose, sodium alginate, gelatin, hydroxyethylcellulose, carboxymethylcellulose, aluminum stearate gel and the like); non-aqueous vehicles, e.g., oil (for example, almond oil or fractionated coconut oil), propylene glycol, ethyl alcohol, or water; preservatives (for example, methyl or propyl p-hydroxybenzoate or sorbic acid); wetting agents such as lecithin; and, if desired, flavoring or coloring agents.

The active agents of this invention may also be administered by non-oral routes. For example, compositions may be formulated for rectal administration as a suppository. For parenteral use, including intravenous, intramuscular, intraperitoneal, or subcutaneous routes, the agents of the invention may be provided in sterile aqueous solutions or suspensions, buffered to an appropriate pH and isotonicity or in parenterally acceptable oil. Suitable aqueous vehicles include Ringer's solution and isotonic sodium chloride. Such forms may be presented in unit-dose form such as ampules or disposable injection devices, in multi-dose forms such as vials from which the appropriate dose may be withdrawn, or in a solid form or pre-concentrate that can be used to prepare an injectable formulation. Illustrative infusion doses range from about 1 to 1000 μg/kg/minute of agent admixed with a pharmaceutical carrier over a period ranging from several minutes to several days.

For topical administration, the agents may be mixed with a pharmaceutical carrier at a concentration of about 0.1% to about 10% of drug to vehicle. Another mode of administering the agents of the invention may utilize a patch formulation to affect transdermal delivery.

Active agents may alternatively be administered in methods of this invention by inhalation, via the nasal or oral routes, e.g., in a spray formulation also containing a suitable carrier.

Exemplary chemical entities useful in methods of the invention will now be described by reference to illustrative synthetic schemes for their general preparation below and the specific examples that follow. Artisans will recognize that, to obtain the various compounds herein, starting materials may be suitably selected so that the ultimately desired substituents will be carried through the reaction scheme with or without protection as appropriate to yield the desired product. Alternatively, it may be necessary or desirable to employ, in the place of the ultimately desired substituent, a suitable group that may be carried through the reaction scheme and replaced as appropriate with the desired substituent. Unless otherwise specified, the variables are as defined above in reference to the most generic form of Formula (I).

Intermediates of formula A4, where Q is —CH₂— are prepared according to Scheme A. Amines A1, where D is O or S, are condensed with phenylacetic acid compounds A2, with heating, to provide fused thiazoles or oxazoles A3. Where D is O, reactions are performed in the presence of an activating agent such as carbonyldiimidazole. The free hydroxyl group is activated using methods known in the art to give compounds A4, where LG is a suitable leaving group (such as chloro, bromo, iodo, tosyl, or mesyl). Preferably, thionyl chloride in CH₂Cl₂ is used to provide compounds A4 where LG is chloro. Analogs of A4 where Q is O are known in the literature or are prepared according to methods described in U.S. Patent Appl. Publ. Nos. US2005/0043378 and US2005/0043379.

In one embodiment, compounds of Formula (I) where D is S are prepared according to Scheme B. Compounds A4, where D is S and LG is a suitable leaving group (such as halo, tosyl, or mesyl), are reacted with amines B1 in the presence of a suitable base (such as Et₃N), in a polar solvent (such as acetonitrile) to give compounds of formula B2, where D is S. Amines B1, where R¹⁰ is R¹ or a suitable nitrogen protecting group, are commercially available or are prepared using methods in the art or methods described in EP 0266576 or WO 01/81347. Where R¹⁰ is R¹, one skilled in the art will recognize compounds B2 are embodiments of Formula (I).

Compounds of formula B2, where D is S, are also prepared by reductive amination protocols. Aldehydes C1, where D is S and R is —CHO or —CH₂CHO, are commercially available or are prepared using methods in the art or methods described in U.S. Patent Appl. PubI. Nos. US2005/0043378 and US2005/0043379. Aldehydes C1 may also be used or purified in a protected form, such as a bisulfite complex. Reaction of aldehydes C1 with amines B1 in the presence of a suitable reducing agent (such as NaCNBH₃ or NaB(OAc)₃H) in a solvent such as 1,2-dichloroethane (DCE), CH₂Cl₂, methanol, or ethanol, and optionally employing an acid catalyst (such as acetic acid or ZnCl₂) provides compounds B2, where D is S.

Alternatively, phenols D1 (prepared using methods analogous to those in the preceding reaction schemes) are reacted with chlorides D2 (where D is S or O) to form compounds B2 where D is S. Compounds of formula D2 are commercially available or are prepared using methods in the art or methods described in Intl. Pat. Appl. No. WO 2006/04475 and L. Zhu, et al. J. Heterocyclic Chem. 2005, 42, 727-730.

Compounds B2, where D is S or O and R¹⁰ is a suitable protecting group (such as tert-butylcarbamoyl group), are converted to compounds of Formula (I) according to Scheme E. Where R¹⁰ is a suitable protecting group, deprotection is effected using generally known methods. For example, where R¹⁰ is a Boc group, deprotection is accomplished using an acid such as HCl or TFA, in a solvent such as Et₂O, dioxane, or CH₂Cl₂. Substituents R¹ are installed by acylation, sulfonylation, reductive amination, or alkylation protocols using methods known in the art to give compounds of Formula (I).

Compounds of Formula (I) may be converted to their corresponding salts using methods described in the art. For example, an amine of Formula (I) is treated with trifluoroacetic acid, HCl, or citric acid in a solvent such as Et₂O, CH₂Cl₂, THF, or MeOH to provide the corresponding salt form.

Compounds prepared according to the schemes described above may be obtained as single enantiomers, diastereomers, or regioisomers, by enantio-, diastero-, or regiospecific synthesis, or by resolution. Compounds prepared according to the schemes above may alternately be obtained as racemic (1:1) or non-racemic (not 1:1) mixtures or as mixtures of diastereomers or regioisomers. Where racemic and non-racemic mixtures of enantiomers are obtained, single enantiomers may be isolated using conventional separation methods known to one skilled in the art, such as chiral chromatography, recrystallization, diastereomeric salt formation, derivatization into diastereomeric adducts, biotransformation, or enzymatic transformation. Where regioisomeric or diastereomeric mixtures are obtained, single isomers may be separated using conventional methods such as chromatography or crystallization.

The following specific examples are provided to further illustrate the invention and various preferred embodiments.

EXAMPLES Chemistry Methods:

In obtaining the compounds described in the examples below and the corresponding analytical data, the following experimental and analytical protocols were followed unless otherwise indicated.

Unless otherwise stated, reaction mixtures were magnetically stirred at room temperature (rt). Where solutions were “dried,” they were generally dried over a drying agent such as Na₂SO₄ or MgSO₄. Where mixtures, solutions, and extracts were “concentrated”, they were typically concentrated on a rotary evaporator under reduced pressure.

Analytical reversed-phase HPLC was performed on an Agilent 1100 Series instrument using one of the following gradients: 1 to 99% acetonitrile/water (0.05% trifluoroacetic acid) over 5.0 min or 7.0 min with a flow rate of 1 mL/min (Waters XTerra MS C18 (5 μm, 4.6×100 mm) column or Phenomenex Synergi max-RP (4 μm, 4.6×150 mm) column) or 1 to 99% acetonitrile/water (20 mM NH₄OH) over 5.0 min or 7.0 min with a flow rate of 1.5 mL/min (Phenomenex Gemeni C18 (5 μm, 3.0×150 mm) column). Analytical reversed phase LC/MS was performed either on an Agilent 1100 Series instrument using 5 to 99% acetonitrile/water (0.05% trifluoroacetic acid) over 5.0 min or 7.0 min with a flow rate of 0.6 mL/min (Waters XTerra RP18 (5 μm, 3.0×100 mm) column) or on a Waters 2790 instrument using 5 to 99% acetonitrile/water (0.1 % formic acid) over 5.0 min with a flow rate of 0.6 mL/min (Waters XTerra RP18 (5 μm, 3.0×100 mm) column).

Preparative reversed phase HPLC was performed on a Dionex APS2000 LC/MS or HPLC with a Phenomenex Gemini C18 (5 μm, 30×100 mm) column or a Waters XBridge C18 (5 μm, 30×100 mm) column and variable gradients of acetonitrile/water (20 mM NH₄OH) at a flow rate of 30 mL/min. Alternatively, the purification was performed with a Phenomenex Gemini C18 (5 μm, 50×100 mm) column or a Waters XBridge C18 (5 μm, 50×100 mm) column and variable gradients of acetonitrile/water (20 mM NH₄OH) at a flow rate of 80 mL/min.

Mass spectra (MS) were obtained on an Agilent series 1100 MSD using electrospray ionization (ESI) in positive mode unless otherwise indicated. Calculated (calcd.) mass corresponds to the exact mass.

Nuclear magnetic resonance (NMR) spectra were obtained on Bruker model DRX spectrometers. The format of the ¹H NMR data below is: chemical shift in ppm downfield of the tetramethylsilane reference (multiplicity, coupling constant J in Hz, integration). NMR interpretation was performed using MestReC or MestReNova software to assign chemical shift and multiplicity. In cases where 2 adjacent peaks of equal or unequal height were observed, these 2 peaks may be labeled either as a multiplet or as a doublet. In the case of a doublet a coupling constant using this software may be assigned. In any given example, one or more protons may not be reported due to obscurity by water and/or solvent peaks.

Chemical names were typically generated using ChemDraw Version 6.0.2 (CambridgeSoft, Cambridge, Mass.) or ACD/Name Version 9 (Advanced Chemistry Development, Toronto, Ontario, Canada).

Step C: (S,S)-2,5-Diaza-bicyclo[2.2.1]heptane-2-carboxylic acid amide hydrochloride. To a solution of (S,S)-2,5-diaza-bicyclo[2.2.1]heptane-2-carboxylic acid tert-butyl ester (35.6 g, 179 mmol) in CH₂Cl₂ (600 mL) was added trimethylsilylisocyanate (82.5 g, 716 mmol). After 2 h at rt, the mixture was concentrated, and the resulting white solid was dissolved in CH₂Cl₂ (500 mL). The solution was then treated with a solution of HCl (4.0 N in 1,4-dioxane, 135 mL). The resulting heterogeneous suspension was then stirred at rt overnight. Upon evaporation of the solvents, the desired product was isolated as a white solid (33 g), which was used directly in the next step. [Note: the mass balance was found to be 104%, which arose from additional HCl that could not be removed by standard evaporation under vacuum]. ¹H NMR (500 MHz, CD₃OD): 4.77 (s, 1H), 4.55 (s, 1H), 3.69 (d, J=12.1 Hz, 1H), 3.64 (d, J=12.1 Hz, 1H), 3.47 (d, J=11.3 Hz, 1H), 3.40 (d, J=11.3 Hz, 1H), 2.22 (d, J=11.5 Hz, 1H), 2.15 (d, J=11.5 Hz, 1H).

A solution of 4-(benzothiazol-2-yloxy)-benzaldehyde (38 g, 149 mmol) in THF (320 mL) was added. The reaction mixture was allowed to stir at rt for 2 h. Sodium triacetoxyborohydride (37.9 g, 180 mmol) was added in 3 equal portions over 10 min at 0° C. The mixture was then stirred at rt overnight. The reaction was diluted with CH₂Cl₂ (500 mL) and 1 N NaOH (300 mL). The layers were allowed to separate and the aqueous layer was further extracted with CH₂Cl₂ (300 mL). The combined organic layers were washed with satd. aq. NaCl (200 mL), dried (MgSO₄) and concentrated. The crude material was dissolved in refluxing EtOAc (400 mL) for 5 h. Upon cooling the solution to rt, the product precipitated as a white solid. This solid was purified by silica gel flash chromatography (4:1 CH₂Cl₂/CH₃OH) to afford the desired product (25 g, 44%) as a white powdery solid. The EtOAc solution recovered after filtration of the white solid was concentrated and purified by silica gel flash chromatography (4:1 CH₂Cl₂/CH₃OH) followed by recrystallization to provide additional desired product as a white solid (8 g, 14%).

Biological Methods: Recombinant Human LTA₄ Hydrolase Assay for LTA₄ Hydrolase Inhibitor Activity

Compounds of the present invention were tested for LTA₄ hydrolase inhibitor activity against recombinant human LTA₄ hydrolase (rhLTA₄H). Vectors were prepared and used to express rhLTA₄H essentially as follows: LTA₄ hydrolase encoding DNA was amplified by polymerase chain reaction (PCR) using a human placental cDNA library as a template. Oligonucleotide primers for the PCR reaction were based on the 5′-end, and the complement of the 3′-end, of the published nucleotide sequence for the coding region of the human LTA₄ hydrolase gene (C. D. Funk et al., Proc. Natl. Acad. Sci. USA 1987, 84:6677-6681). The amplified 1.9 kb DNA fragment encoding LTA₄ hydrolase was isolated and cloned into the pFastBacl vector (Invitrogen). Recombinant baculovirus was generated as described by the manufacturer, and used to infect Spodoptera frugiperda (Sf-9) cells. Recombinant LTA₄ hydrolase enzyme was purified from the infected Sf-9 cells essentially as described by J. K. Gierse et al. (Protein Expression and Purification 1993, 4:358-366). The purified enzyme solution was adjusted to contain 0.29 mg/mL LTA₄ hydrolase, 50 mM Tris (pH 8.0), 150 mM NaCl, 5 mM dithiothreitol, 50% glycerol, and EDTA-free Complete protease inhibitor cocktail (Roche). The specific activity of the enzyme was about 3.8 μmol/min/mg.

LTA₄ substrate was prepared from the methyl ester of LTA₄ (Cayman Chemical) by treatment with 67 equiv of NaOH under nitrogen at rt for 40 min. The LTA₄ substrate in its free acid form was kept frozen at −80° C. until needed. Each compound was diluted to different concentrations in assay buffer (0.1 M potassium phosphate (pH 7.4), 5 mg/mL fatty acid free BSA) containing 10% DMSO. A 25-uL aliquot of each compound dilution was incubated for 10 min at rt with an equal volume of assay buffer containing 36 ng of recombinant human LTA₄H. The solution was then adjusted to 200 μL with assay buffer. LTA₄ (free acid) was thawed and diluted in assay buffer to a concentration of 357 ng/mL, and 25 μL (9 ng) of LTA₄ substrate was added to the reaction mixture (total volume=225 μL) at time zero. Each reaction was carried out at rt for 10 min. The reaction was stopped by diluting 10 μL of the reaction mixture with 200 μL of assay buffer. LTB₄ was quantified in the diluted sample by a commercially available enzyme-linked immunoassay (Cayman Chemical Co.), as recommended by the manufacturer. Positive controls, under essentially identical conditions but without addition of an inhibitor compound, and negative controls, containing all assay components except enzyme, were routinely run in each experiment. IC₅₀ values were determined by fitting the activity data at different compound concentrations to a 4-parameter equation using the Grafit program (Erithacus software).

Results for the compounds tested in this assay are presented in Table 1 as an average of results obtained.
